AbstractAbstract
[en] The dynamical polarization potential corresponding to simple, physical two-channel model is derived and examined paying particular attention to its analytic properties. This enables us to illustrate explicitly the emergence of the general dispersive and retardation features expected from the imposition of causality. The energy dependence of the potential and the associated nonlocality in time, expressed by its Fourier transform, are explored. A physical interpretation of the time nonlocality in terms of the time delay due to the excitation of the inelastic channel will be given

AbstractAbstract
[en] This summary begins with some general remarks about what we mean by an optical potential, how it is defined and the ways it can be determined, either microscopically from the nucleon-nucleon interactions, or by phenomenological analysis of the experimental data, or in some intermediate way. The next Section 3 is devoted to the microscopic potentials themselves, both global for a range of nuclei and particular when the properties of particular nuclei are introduced into the calculation. Section 4 considers the ways of adding extra theoretical or phenomenological effective potentials to the standard optical potential to account for a recognized physical effect. Sections 5, 6 and 7 are devoted to new experimental data and phenomenological analyses of nucleon, light and heavy ion interactions, and Section 8 to some concluding remarks. (orig./AH)

Diese Zusammenfassung beginnt mit einigen allgemeinen Bemerkungen ueber das, was wir als optisches Potential verstehen, wie es definiert ist, und die Art, wie es bestimmt werden kann; entweder mikroskopisch ueber die Nukleon-Nukleon-Wechselwirkung oder ueber eine phaenomenologische Analyse experimenteller Daten oder ueber einen Mittelweg. Der naechste Teil 3 ist den mikroskopischen Potentialen selbst gewidmet, jeweils global fuer einen Bereich von Kernen und speziell wenn die Eigenschaften des einzelnen Kerns in die Berechnung einbezogen werden. Teil 4 betrachtet die Wege, um zusaetzliche theoretische und phaenomenologische effektive Potentiale zum Standard-optischen Potential zuzufuegen, um einem erkannten physikalischen Effekt Rechnung zu tragen. Die Teile 5, 6, 7 sind neueren experimentellen Daten und phaenomenologischen Analysen von Nukleonen, Leicht-und Schwerionenwechselwirkung gewidmet. Teil 8 ist einigen zusammefassenden Bemerkungen gewidmet. (orig./AH)Primary Subject

AbstractAbstract
[en] The classical single-particle motion in a potential with quadrupole and octupole deformation is investigated. By both numerical and analytical means, the appearance of chaotic motion is related to the properties of the curvature of the potential surface. (author)

AbstractAbstract
[en] The foundations of the inverse mean field method (Imefim) and its relation to traditional approaches are discussed. Imefim predicts the energy dependence of the real central (nuclear) part of the optical model potential to have the functional form (1+eEsub(p))-3. Treating for the time being the constant e as an adjustable parameter, this prediction is shown to compare nicely with well-established formal and heuristic results. (orig.)
